xml数据资源更改时刷新组合框？
我实现了一个应用程序，我使用一个组合框，这个组合框填充了 xml 文件中的项目。这很好用。绑定是：
<ComboBox ItemsSource="{Binding Source={StaticResource Vakken}}" DisplayMemberPath="@Name" Height="23" HorizontalAlignment="Left" Margin="215,67,0,0" Name="comboBox1" VerticalAlignment="Top" Width="120" SelectionChanged="comboBox1_SelectionChanged" />
但我还有一个按钮，允许用户将项目添加到 xml 文件中。将项目添加到 xml 文件中（因此写入方法有效）非常有效，但更改不会提交到组合框中。那么有没有办法刷新这个组合框或类似的东西。因为我刚刚添加的项目不在组合框中？
I implemented an application, i use a combobox, and this combobox is filled with items out of a xml file. This works fine. Binding is:
<ComboBox ItemsSource="{Binding Source={StaticResource Vakken}}" DisplayMemberPath="@Name" Height="23" HorizontalAlignment="Left" Margin="215,67,0,0" Name="comboBox1" VerticalAlignment="Top" Width="120" SelectionChanged="comboBox1_SelectionChanged" />
But i also have a button, which allows the user to add an item to the xml file. It works perfectly to add a item to the xml file( so the writing method works) but the changes are not committed in the combobox. So is there anyway to refresh this combobox or something like that. Because the item which i just added, doesn't stand in the combobox?

XML 操作是我会尽量避免的，它对于小型数据传输来说是一种非常好的格式，并且很容易解析和序列化等等，但它不是现有的编程语言和框架的本机。
我会将 XML 解析为
ObservableCollectiononce，如果您绑定到该 XML，您的 ComboBox 将被更新（如果您必须的话，您甚至可以反过来更新 XML）通过订阅CollectionChanged事件并将集合序列化回 XML）。XML manipulation is something i would try to avoid, it's a very nice format for small data-transfer and nice to parse from and serialize to and all that but it's not native to the programming language and framework at hand.
I would parse the XML to an
ObservableCollection<T>once, if you bind to that your ComboBox will be updated (and you could in turn even update the XML if you must by subscribing to theCollectionChangedevent and serializing the collection back to XML).
